F=%287%2F4%29%28n-37%29+...set F=0 to solve for n

0=%287%2F4%29%28n-37%29+

0=%287%2F4%29n-%287%2F4%2937%29+

0=%287n%2F4%29-%287%2A37%2F4%29%29+....both sides multiply by 4

0%2A4=%287n%2F4%29%2A4-%287%2A37%2F4%29%2A4%29%29+

0=7n-7%2A37+

7%2A37=7n+

7%2A37%2F7=n+

cross%287%29%2A37%2Fcross%287%29=n+

F=7over4(n-37)
Solve for N
Use Integers or Fractions for any numbers in the expression

Why do you have n in the equation, but ask that the equation be solved for N. n and N are two different things. Assuming that they are similar, we have:

F+=+7%2F%284%28n+-+37%29%29

F+=+7%2F%284n+-+148%29

F(4n - 148) = 7 ------ Cross-multiplying

4Fn - 148F = 7

4Fn = 7 + 148F

highlight_green%28n+=+%287+%2B+148F%29%2F4F%29, or highlight_green%28n+=+7%2F4F+%2B+37%29
